Ross William Hamilton/The OregonianMichael Clay (center) says the Ducks are almost back to their exhausting pace of the 2010 season, but believes they can go even faster in 2011.

Day 11 is in the books for the Oregon football team and yes, that WAS redshirt freshman Dior Mathis you saw lining up at wide receiver.

The Ducks practiced Friday at Kilkenny Field after some reshuffling that involved moving Mathis to receiver, a position he knows well.

Mathis, a 5-foot-9 standout athlete from Detroit, was an All-American at Cass High School playing both positions; scouting services raved about his athleticism when he signed with Oregon. Coach Chip Kelly said Mathis had a great attitude about the move.

"I don't know if we have a new receiver, we're just trying to line up some spots for some kids," Kelly said. "He's the one kid in the secondary we thought we could cross train. It'll add some depth to us ... He can fly, No. 1. He's on our track team, he's got great speed. If you looked at his high school tape he was a dynamic player with the ball in his hands."

Kelly said the Mathis experiment could last two days or the whole season -- at this point, it's wait and see.

"All the time, we're trying to find spots for everybody, and utilize everybody," Kelly said.

In other (injury-related) news, tight end Curtis White, who was a star at Sheldon High School in Eugene before suiting up for the Ducks, looks to be out at least two weeks according to Kelly. Details of White's injury have not been disclosed but he was carted off the field on Thursday and seen later Thursday evening on crutches with his left leg and foot wrapped.

Josh Huff did not practice on Friday, either.

Linebacker Michael Clay said the Ducks haven't quite yet reached their pace from the 2010 season but that they're "working up to it and we're really close."

"Sometimes I feel like we're not going fast but we actually are," Clay said. "We're in that mode right now where we feel really good."

As for players' conditioning, Clay said it's been so far, so good.

""No one that I know of has passed out yet," Clay laughed. "We're all alive and kicking still."
